the 125 has a single fx5 on it with 3 boxes of media and thats it ... works great .. the sponges do great for mech and bio and the rings hold all the other BB .. never have problems and the water is clear ...
the 150 has a fx5 same set up but also a rena3 with a stock set up .. and that tank is also great ...
im not huge on OVER kill .. but i do have plenty of filtration .. no need to have 2 fx5's on a 75 gal tank .. waste of money and filtration ..
